brake lock differential

I'm wondering how a LSD and traction control can go hand in hand on a Jeep? If a Jeep has LSD does traction control not work in that axle, or does traction control kick in before the LSD and therefore the LSD is pointless unless I completely turn off traction control?

With all the money spent on lockers and axles, I'm surprised no-one came up with a traction control map for rock crawling. It can potentially offer a much cheaper, less invasive solution for most people. I think the BLD can be better if it applied brakes more aggressively/quicker on...
